This one came up on abebooks.com and is sold by The Tolkien Bookshelf. What do you guys think?

Description: A copy of the 1st edition of Gottfried Keller's, 'Werke, Band 3, Der Grune Heinrich, Fragmente Aus Der Ersten Fassung, Dramatische Fragmente'. The significant part of this book is the signature of J.R.R. Tolkien to the front endpaper. Front endpaper has previous owners name and 'The Queens College, Oxford", with the Tolkien signature below. Possibly from a former student of Tolkien's. Appears legitimate, but no other provenance known.

To me, the signature looks a rather similar to some of the dodgy blue-pen ones which Tolkien Bookshelf has - presumably inadvertently - had up for sale in the past. With no provenance, I would probably avoid.

I wasn't thinking of purchasing it; the "no other provenance known" already makes the item questionable, but it also seemed to me to be rather similar to some of the other sketchy signatures that have been circulating lately--same style and similar blue ink (as Stu notes). I just wanted to post it and see if you guys agreed. If this is, in fact, a fake, should someone contact the seller? What do you guys think?
